Description

Technical Field

[0001] The utility model relates to the field of medical technology, in particular to an occlusion tester for tooth implant testing. Background Art

[0002] Dental implants, also known as dental implants or artificial dental implants, are a modern dental technology that aims to restore the function and aesthetics of cavities caused by missing teeth. It is a restoration method that implants made of artificial materials are implanted into the alveolar bone of the toothless area, and then a crown is made on it after it combines with the bone tissue. After the dental implant is completed, in order to be able to test the bite force, a bite tester is generally used to test it, thereby determining the strength of the bite force.

[0003] In the prior art, bite detectors are generally made of hard materials and apply pressure to the sensor to obtain the corresponding bite force. Although this method can quickly obtain the corresponding bite force, when in use, the detector cannot be effectively adjusted according to the user population. The teeth of the elderly and children are relatively weaker than those of adults. During the detection process, the corresponding pressure cannot be effectively adjusted, and the test pressure cannot be gradually increased. When pressure is applied to the detector, it is easy to cause damage to the inside of the mouth. Utility Model Content

[0004] The purpose of the utility model is to provide an occlusal tester for dental implant testing, so as to solve the problem that the detector cannot be effectively adjusted according to the user population, wherein the teeth of the elderly and children are relatively weaker than those of adults, and the corresponding pressure cannot be effectively adjusted during the testing process, and the test pressure cannot be gradually increased, which easily causes damage to the inside of the oral cavity when pressure is applied to the detector.

[0005] The utility model provides the following technical solution: an occlusion tester for dental implant testing, comprising a handle frame, an end portion of the handle frame being fixedly connected to an outer frame, an outer side wall of the outer frame being symmetrically slidably connected to a fixing rod, ends of two fixing rods being fixedly connected to an upper support frame and a lower support frame respectively, the other end of the fixing rod being located inside the outer frame, and the end portion being fixedly connected to a cover plate, and a flexible pressure-bearing structure for convenient detection is provided inside the outer frame at the middle of the two cover plates.

[0006] By adopting the above scheme, by adjusting the positions of the upper support frame and the lower support frame, biting actions of different angles and strengths can be simulated, which provides the possibility for personalized testing. The flexible pressure structure is located in the middle of the two cover plates, which can accurately sense and record the pressure and deformation generated during the biting process, and provide reliable data for evaluating the stress conditions of the dental implants. In addition, the design of the flexible pressure structure enables the tester to cause less discomfort to the patient during the test, thereby improving the comfort of the test.

[0007] As a preferred embodiment of the above technical solution, the flexible pressure structure includes a cover plate fixedly connected to the inner wall of the outer frame, and the end faces of the two cover plates are in contact with the outer wall of the airbag, the gas inlet end of the airbag is fixedly connected to an air intake pipe, the end of the air intake pipe is fixedly connected to an air pressure ball, the outer wall of the air pressure ball is installed with a return valve, the air intake pipe and the air pressure ball are located on the outer wall of the handle frame, and the outer wall of the air intake pipe is installed with a one-way valve.

[0008] By adopting the above solution, the outer wall of the airbag contacts the end faces of the two cover plates, ensuring that the pressure can be evenly distributed on the airbag during biting, thereby accurately measuring the biting force. The setting of the air inlet pipe and the air pressure ball allows the user to squeeze the air pressure ball to fill the airbag with gas, thereby adjusting the hardness and pressure sensation of the airbag.

[0009] As a preferred embodiment of the above technical solution, the gas discharge end of the airbag is fixedly connected to an outlet pipe, an outer wall of the outlet pipe is installed with an electrically controlled exhaust valve, and the outer side wall of the airbag is fixedly connected to a catheter.

[0010] With the above scheme, the introduction of the electronically controlled exhaust valve enables the gas discharge of the airbag to be quickly and precisely controlled. After the test is completed, the electronically controlled exhaust valve can be quickly opened through electronic control to allow the gas in the airbag to be quickly discharged in preparation for the next test. The precise control of the electronically controlled exhaust valve can ensure that the gas in the airbag will not be suddenly released during the test, thereby avoiding possible accidental injury to the patient.

[0011] As a preferred embodiment of the above technical solution, an air pressure sensor is fixedly connected to the inner bottom end of the handle frame, and the end of the conduit is fixedly connected to the access end of the air pressure sensor. The inner bottom end of the handle frame is located on one side of the air pressure sensor and is fixedly connected to a communication module and a main control chip.

[0012] Using the above solution, the air pressure sensor is connected to the airbag through a catheter, which can monitor the air pressure changes in the airbag in real time and accurately, thereby reflecting the pressure changes during the occlusion process. The main control chip, as the core of the system, can receive the signal transmitted by the air pressure sensor and perform fast and accurate data processing and analysis. The communication module allows the tester to communicate wirelessly with the host computer or other equipment and transmit test data in real time.

[0013] As a preferred embodiment of the above technical solution, the inner bottom end of the handle frame is fixedly connected to a battery at one side of the communication module, and the outer side wall of the handle frame is fixedly connected to a charging interface of the battery charging access terminal.

[0014] With the above solution, the addition of a storage battery enables the tester to work without relying on an external power source, which greatly improves the portability and independence of the device.

[0015] As a preferred embodiment of the above technical solution, a display screen is fixedly connected to the upper top of the handle frame, and an indicator light is provided at the upper top of the handle frame located on one side of the display screen.

[0016] The above scheme is adopted, in which the display screen is connected to the main control chip, and the main control chip is controlled and connected with the indicator light, the electric control exhaust valve, the air pressure sensor and the communication module. The main control chip adopts the STM32F103RCT6 microcontroller, the air pressure sensor is the Freescale MPXV4006G sensor, and the communication module model is NRF24L01. The operation of the indicator light, the electric control exhaust valve, the air pressure sensor and the communication module are controlled by the display screen and the main control chip.

[0017] As a preferred embodiment of the above technical solution, a sliding groove is provided on the outer side wall of the handle frame, a slider is slidably connected inside the sliding groove, a connecting rod is fixedly connected to the outer side wall of the slider, and the end of the connecting rod is fixedly connected to a limiting seat of a limiting air pressure ball.

[0018] With the above solution, the design of the slide groove and the slider allows the user to easily adjust the position of the limit pressure ball, and the limit pressure ball can limit the pressure ball and control the pressure ball when not in use.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, a flexible pressure-bearing structure is provided. During use, the air pressure ball can be pressed to allow gas to be delivered into the interior of the airbag through the air inlet pipe. At this time, the airbag is pressurized and expanded. When the airbag expands to a certain extent, it will stop expanding. At this time, the gas pressure inside the airbag will rise, and the user will feel resistance when applying pressure to the airbag. By delivering gas to the interior of the airbag, the gas pressure inside the airbag is changed, thereby achieving the purpose of gradually increasing the test pressure during the detection process.

[0028] like Figure 2 and Figure 4 As shown, the flexible pressure-bearing structure includes a cover plate 41 fixedly connected to the inner wall of the outer frame 11, and the end faces of the two cover plates 41 are in contact with the outer wall of the airbag 4. The airbag 4 is compressed to cause it to deform. At this time, the air pressure change inside the airbag 4 can be observed. The gas inlet end of the airbag 4 is fixedly connected to an air inlet pipe 32, and the end of the air inlet pipe 32 is fixedly connected to an air pressure ball 3. The outer wall of the air pressure ball 3 is provided with an air return valve 31. By pressing the air pressure ball 3, gas enters the interior of the compressed airbag 4, and the air pressure ball 3 is reset through the air return valve 31.

When the airbag 4 is pressurized, the gas will enter the air pressure sensor 25 through the conduit 45. At this time, the air pressure sensor 25 can observe the pressure of the airbag 4. The inner bottom end of the handle frame 1 is located on one side of the air pressure sensor 25 and is fixedly connected with the communication module 23 and the main control chip 24.

By delivering gas to the inside of the airbag 4, the gas pressure inside the airbag 4 is changed, so as to achieve the purpose of gradually increasing the test pressure during the detection process. When the detection is completed, the electronically controlled exhaust valve 44 can be started by controlling the display screen 2, and the gas inside the airbag 4 will be discharged through the outlet pipe 43.
